1 / 32 page  1. General description The PCA9570 is a CMOS device that provides 4 bits of General Purpose parallel Output (GPO) expansion in low voltage processor and handheld battery powered mobile applications. It operates at 1 MHz I2C-bus speeds while maintaining backward compatibility to Fast-mode (400 kHz) and Standard-mode (100 kHz). The PCA9570 is a streamlined GPO that consists of 4-bit push-pull outputs that offer low current consumption, small packaging options and a low operating voltage range of 1.1 V to 3.6 V. The latched outputs are symmetrical 4 mA current drive capability at 3.3 V to drive various control logic. The PCA9570 output expander provides a simple solution when additional outputs are needed while keeping interconnections and floor space to a minimum, for example, in battery powered mobile applications where PCBs are crowded for interfacing to sensors, push buttons, etc. The PCA9570 contains an internal Power-On Reset (POR) and a Software Reset feature that initializes the device to its default state. 2. Features and benefits 1MHz I2C-bus interface with 6 mA SDA sink capability for lightly loaded buses (<100 pF) and improved power consumption Compliant with the I2C-bus Fast and Standard modes 1.1 V to 3.6 V operation Latched outputs with a sink/source capability of 4 mA at 3.3 V Readable device ID (manufacturer, device type, and revision) Software Reset Power-On Reset Low standby current 40 C to +85 C operation ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101 Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA Packages offered: TSSOP8, XQFN8 (0.4 mm lead pitch), XQFN8 (0.5 mm lead pitch) 3. Applications Smart phones and tablets Portable medical equipment Portable instrumentation and test measurement PCA9570 Remote 4-bit general purpose outputs for 1 MHz I2C-bus Rev. 4 — 17 September 2014 Product data sheet |
